Caption: This image illustrates how the channels in a polymer electrolyte membrane material change when you stretch it. On the left is an unstretched sample of the material. The middle sample has been stretched at a ratio of 2:1, while the sample on the right, which shows the most channel alignment, has been stretched at a ratio of 4:1.
